STUlVlP-BURNER.

SPECIFICATION forming part of Letters Patent No. 769,708, dated September 13, 1904:.

Application filed March 25, 1904.

To to 1117mm if Yarn concern.-

Be it known that I, CHARLES T. MCCARROLL, a citizen of the United States, residing at Ottumwa, in the county of \Vapello and State of Iowa, have invented a new and useful Stump- Burner, of which the following is a specification.

The invention relates to improvements in stump-burners.

The object of the present invention is to improve the eonstruction of stump-burners and to provide a simple and comparatively inexpensive one adapted to be readily set up around the stump and capable of effectively burning both dry and green stumps.

A further object of the invention is to provide a stump-burner adapted to burn a stump and its large roots for a distance of' several feet beneath the surface of the soil to clear land and prevent the roots from interfering with a plow or other cultivating device.

The invention also has for its object to provide means for directing a blast of air upon a stump and to enable the same to be readily extended and arranged in the desired direction for consuming the larger roots.

"ith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to Without departing from the spirit or sacrific ing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a stump-burner constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a similar view, the upper sections of the casing being removed and the air-blast tube being extended for burning a root.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 and 2 designate cylindrical sections of an extensible casing which is composed of the Serial No. 199,998. (No model.)

bottom section 1 and a plurality of upper sections 2, which may be of any desired number to secure a casing of the desired height, and as the sections 2 and a cover 3 are of the same diameter one or more sections may be used, and the cover may be arranged upon one of the upper sections 2, as illustrated in Figs. 1 and 2 of the drawings, or upon the bottom section 1, as illustrated in Fig. 3. The section 1 is designed to be arranged upon the ground and around the stump, as illustrated in Fig. 2 of the drawings, and in practice the ground will be leveled or a slight trench will be dug to receive the lower section. The lower edge of the lower section is designed to be partially embedded in the ground to provide an air-tight connection at the bottom to prevent air from entering at that point and interfering with the draft of the stump-burner. The bottom section is provided with a plurality of draft-openings preferably flanged, as shown in Figs. 2 and 3, and provided with caps or covers 5, which may be fitted within or around the flanges of the bottom section or provided with rotary dampers or cut-ofl's 6, having openings adapted to register to a greater or less degree with corresponding openings of the caps and to be carried out of register for controlling the draft. These draft-openings are mainly employed while the stump-burner is drying a green stump.

The sections 2 are provided at their lower edges with annular grooves to receive the upper edges of the contiguous sections, the grooves being preferably formed by flaring the lower edges '7 of the sections 2 outward slightly and by providing an interiorly-arranged flange or ring 8 to co perate with the lower edges 7. The flange or ring is riveted or otherwise secured to its section 2, and its lower portion is crimped or contracted to provide a tapering annular groove or space between it and the lower edge of the section, whereby the upper edge of the contiguous section may be fitted tightly within the groove. By this construction an air-tight joint or connection between the sections is provided. The cap, which is provided with a depending interiorly-arranged flange 9, also has an interiorly-arranged flange or ring 10, cooperating with the flange 9 to form a tapering groove to receive the upper edge of the contiguous section.

The cover or top of the casing is provided with a plurality of openings 11 and 12, having upwardly-extending annular flanges. These openings are preferably arranged as shown in Fig. 1, the opening 11 being located at the center of the top or cover and the opening 12 being arranged around the same. Any number of these openings may be provided, and they are of the same diameter. The central opening receives a smoke stack or pipe 13, and the other openings are adapted to permit an air-blast pipe or tube 14 to be arranged in the desired position for burning a stump or the roots thereof. The top openings 12 not in use are covered by caps or closures 15. The air-blast pipe or tube 14: is tapering, as shown, and it is preferably provided with an exteteriorly -arranged hood 16, consisting of a large elbow or section having aflaring mouth 16, adapted to be turned to receive any Wind that may be blowing, whereby the current or blast of air is increased. A plurality of these air-blast tubes or pipes may be simultaneously used, according to the size of the stump, and in burning a dry stump the fuel is placed around the stump, being introduced through the top openings of the stump-burner, and as soon as the stump is ignited the blast of air direct upon the same Will cause the stump to be rapidly consumed. As the stump is consumed the sections of the casing may be reduced in numher, and to facilitate the same they are provided at opposite sides with handles 17 The air-blast tubes may be of different lengths, and they are provided at their lower reduced ends with elbow sections 18 and straight sections 19, which may be of any desired number and which may be readily turned in the desired direction for directing the blast of air upon a root, whereby the large roots of a stump may be consumed for a distance of several feet beneath the surface of the ground in the manner indicated in Fig. 3 of the drawlngs.

When it is desired to burn a green stump, it is first dried by burning fuel around the stump and within the casing until the stump takes fire. The bottom draft-openings are employed for controlling the draft while the stump is being dried. As soon as the stump is thoroughly dried and begins to burn one or more of the air-blast tubes are placed in position, and the stump will then be consumed without the use of any more fuel.

The cover or top of the casing is also provided with opposite handles 20 for enabling it to be readily removed from and replaced on the casing. The smoke-pipe 13 may be supported by a plurality of wire stays or braces 21, detachably engaging perforated ears or flanges 22 and 23 of the smoke-pipe and the top or cover.

It will be seen that the stump-burner is exceedingly simple and inexpensive in construction, that the extensible casing may be quickly set up over a stump, and that both a green and dry stump may be eflectively consumed. Also it Will be clear that the stump-burner is adapted to consume a stump and its roots for a distance of several feet beneath the surface of the ground and that the large roots may be followed up and consumed for some distance from the stump.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
